Upgrades complete

It was a rough day, but the upgrade of the last server is complete. There were some problems in transferring over that caused some things on the site to break. It took a few hours to figure out what was wrong. With this I think I can move away from the hardware problems we have had and get back to working on course content.

There are a number of courses that have been asked for, including more algebra courses, a course on trigonometry, and a course on Fourier transforms. It is interesting to me that the most requested courses recently have been math courses. My on plan is to try to alternate between the math courses and engineering and measurement courses.
